If you're going to chat sh*t about Gigi Hadid and Kendall Jenner, you better know that you'll have hot momma Yolanda to answer to.

And that's exactly what happened the other day when model and actress Rebecca Romjin got her claws out at KenGi. Speaking to Entertainment Tonight, she said:

"No one has proven yet that numbers of followers translates to revenue. I know a lot of people — legitimate fashion people — can't stand it. Hate it that these, you know, social media stars are now the supermodels in fashion. They are not true supermodels."

Meow! This cat's out the bag!

Naturally, proud mama Yolanda (who also used to be a model) unleashed her wrath upon Rebecca for trying to imply that her baby girl Gigi wasn't hardworking or successful.
